Method:
1. Prepare the meatloaf mixture:
Preheat your oven to 350°F (175°C). Grease a loaf pan or line it with parchment paper for easy removal.
In a large bowl, combine the ground beef, chopped onion, minced garlic, breadcrumbs, milk, egg, French onion soup mix, Worcestershire sauce, salt, and pepper. Mix everything until just combined. Be careful not to overwork the mixture to keep the meatloaf tender.
2. Shape the meatloaf:
Transfer the meat mixture into the prepared loaf pan and press it down gently to shape it evenly. Alternatively, you can form it into a free-standing loaf and place it on a lined baking sheet if you prefer.
3. Bake the meatloaf:
Place the meatloaf in the preheated oven and bake for 45-50 minutes, or until the meatloaf is cooked through (internal temperature should reach 160°F/71°C).
4. Prepare the topping:
While the meatloaf is baking, in a small saucepan, heat the French onion soup over medium heat. Simmer for 5 minutes to thicken slightly.
When the meatloaf is done, remove it from the oven and pour the French onion soup over the top of the meatloaf.
Sprinkle the shredded cheese evenly over the soup layer.
5. Finish baking:
Return the meatloaf to the oven for an additional 10-15 minutes, or until the cheese is melted and bubbly, and the topping is slightly golden.
